Eye Surgery TRIZ Cases
- Integrated Light Guide with Cutting Edge for Ophthalmic Incision
An integrated light guide combines a cutting edge and illumination channel to incise the sclera, eliminating separate trocars and reducing procedure time.
- Aspiration Port Positioning for Surgical Cassette Fluid Control
Bottom-mounted aspiration ports minimize surface disturbance in surgical cassette chambers to enable precise fluid level sensing.
- Flexible Cannula Base for Ophthalmic Stability
A flexible cannula base conforms to the eyeball surface during surgical tool movement.
- Capsular Tension Ring Injector With Dual-Threshold Guide
A disposable injector uses a spring-loaded plunger and guide arm to carry a capsular tension ring into the throughfeed channel.
- Surgical System Priming via High Vacuum Pulses
High vacuum pulses dislodge residual entrained air from surgical system fluid passages, resolving compliance issues caused by remaining gas pockets.
- Aperiodic Pulse Control for Phacoemulsification
An ophthalmic surgical pulse control device uses aperiodic pulse packets to break down lens particles while preventing corneal heating from standing waves.
- Covalent Phenolic Scavenger Bonding in Ophthalmic Viscoelastic Devices
A viscoelastic polymer covalently bonds phenolic scavengers to stabilize free radical absorption at the surgical site.
- Adjustable Support for Small Gauge Surgical Instruments
Segmented instrument shafts with graduated diameters resolve the trade-off between minimal incision size and operational stiffness.
- Grooved Needle Tip for Ultrasonic Phacoemulsification
Asymmetric grooved needle tip transforms rotary motion into sweeping action, resolving clogging and compatibility issues in torsional phacoemulsification.
- Movable Irrigation Nozzle for Ocular Particle Therapy
A movable irradiation nozzle directs charged particle beams toward the patient's eye using a pencil beam scanning subsystem.
